    • A gas concentration measurement device which utilizes a TDLAS measurement method, and in which the phase-sensitive detection can be performed by digital processing using an integer-arithmetic device, is provided. In the gas concentration measurement device according to the present invention, AC components corresponding to integer multiples of a modulation frequency f contained in an input signal are removed by taking a moving average of data obtained from an output signal of a multiplier 62 for a period of time corresponding to one cycle of the modulation frequency f . As a result, a DC component in the output signal of a digital filter 63 relatively increases, making it easier to extract the DC component by a digital low-pass filter 64, so that a sufficiently accurate phase-sensitive detection can be made even if a digital processing based on integer arithmetic is used.

    • Within a container 1 which is storing a sample is generated a regularly arranged electric field distribution by an impression of a voltage upon an electrode pair 2 provided within the container 1, thereby generating diffraction grating formed by a density modulation of particles within the sample within the container 1, there is obtained information upon a diffusion of the particles based upon a temporal change in an extinction process of an intensity of a diffracted light beam obtained by irradiating a light beam upon the diffraction grating formed by the density modulation of the particles, the electrodes 21, 22 constituting the electrode pair 2 are configured to have multiple linear electrode teeth 21a, 22a parallel with each other, the electrodes 21, 22 are arranged such that the electrode teeth 21a of one electrode 21 are inserted between the electrode teeth 22a of the other electrode 22, thereby increasing the width of the diffraction grating formed by the density modulation of the particles, and a ratio of a component of the diffracted light beam thereof included in an entire diffracted light beam is increased to increase sensitivity of a measurement. As a result, there is provided an optical measuring device which can measure the information upon the diffusion of the particles movably dispersed within a medium at a high sensitivity and with an excellent S/N ratio.

    • A plurality of storage pixels within each unit pixel are arranged successively so that signal electrons for each storage pixel are moved independently through the storage pixels. Signal electrons newly generated in a photosensitive pixel are added to relevant signal electrons among the signal electrons moved independently through the storage pixels. That is, signal electrons generated in the photosensitive pixel for each of highly relevant frames are superimposed in the same storage pixel and stored in each storage pixel. The signal electrons stored in each storage pixel are subsequently amplified in and outputted from an output amplifier only once. Thus, read noise occurs only once at the output amplifier, to obtain images of high signal-to-noise ratio.
    • 每个单位像素内的多个存储像素被连续布置,使得每个存储像素的信号电子独立地通过存储像素移动。 在感光像素中新生成的信号电子被添加到通过存储像素独立移动的信号电子之间的相关信号电子。 也就是说,在感光像素中产生的每个高度相关的帧的信号电子被叠加在相同的存储像素中并存储在每个存储像素中。 存储在每个存储像素中的信号电子随后在输出放大器中被放大并输出一次。 因此,读出噪声仅在输出放大器发生一次,以获得高信噪比的图像。

    • A floating diffusion region is formed at an edge of a light-receiving surface of an embedded photodiode, with a transfer gate electrode located therebetween. A first region, with radially extending portions centered on the FD region, and a second region, located to the outside of the first region, are created in the substantially sector-shaped light-receiving surface. A dopant whose conductivity type is the same as the signal charges to be collected in the first region are introduced, whereby an electric field for moving the signal charges from the radially extending sections towards the center is created due to a three-dimensional field effect. As a result, the charge-transfer time is reduced. Additionally, since a circuit element in the subsequent stage can be placed adjacent to the floating diffusion region, the parasitic capacitance of the floating diffusion region can be reduced and a highly sensitive element can be obtained.
